IMPROVEMENT IN SASH-HOLDERS.

Specification forming part of Letters Patent No. 123,111, dated January30, 1872.

To all whom it may concern:

Be it known that I, W. HASKELL KING, of Newark, in the county of Essexand State of New Jersey, have invented a new and useful ImprovementinSash-Lifters and Holders; and I do hereby declare the following to be afull, clear, and exact description thereof sufficient to enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing making part of this specification, in which- Figure1 is avertical section of the improved sash-lifter and holder. Fig. 2 isa vertical section of the case containing a friction-roller andoperating-shaft. Fig. 3 is a front view of the same. Fig. 4=is afrontview ofthe same, showing the anti-friction roller, the operating-shaft,and spring removed. Fig. 5 is a transverse section of a sash-frame,showing the formation of the guide-plate.

This inventionis designed as an improvement upon the patent of W.Haskell King and Jared Rowland, dated February21, 1871, No. 111,946, foran improvement in sash-holders; and to this end this present inventionconsists: First, in. arranging within the jamb of a windowframe ametallic plate, which is provided or formed with a curved or ellipticalsocket to receive a curved bolt or shaft having a frictionwheel and areacting spring, all of which act in connection with inclined surfaceson the sides of a sash in such a manner as to hold the same in anydesired position, and at the same time assist in elevating the san1ethatis, to form a lifting power, whereby an upward movement is imparted tosaid sash. Second, the invention consists in forming a recess in thecurved or elliptical socket within which is arranged an anti or otherfriction-roller, for a purpose hereinafter mentioned.

Similar letters of reference indicate corresponding parts in eachfigure.

The letter A designates the jamb of a window-irame, and B the sash, bothof which are of the ordinary form and construction. 0 is a metallicfaceplate, provided with holes a a, to receive screws, by which meansthe said plate is secured to the jamb. This plate is formed or providedwith a curved or elliptical socket, D, within which is arranged a curvedbolt or shaft, E, bearing on its front end or head a, and

a friction-wheel, d, which operates on an incline formed or placed uponthe sash B. A metallic or other suitable reacting spring, F, is arrangedin the socket D, in the rear ofthe curved bolt or shaft E. This springpreferably surrounds the shank e of the bolt E, and has one end pressingagainst the shoulder of the head 0, while the other end has its seatagainst the end of the socket D. This spring is thus arranged so that,owing to its tension, it will constantly press outward the curved boltor shaft E, so that the friction-wheel 01 will operate upon or in aguide-groove of the inclined surfaces of the sash, by which means thesash will be retained in any desired position, the spring and boltacting in connection with the inclines of the sash in such manner thatit forms its own lifting or elevating power, and imparts to the sash anupward tendency-that is, the sash is elevated with less power than isrequired to lower it. The inclined surfaces of the sash are preferablycovered with a metallic plate, I, which is formed with a guide-groove,9, corresponding with the guide-groove h of the sash.

By the employment of the grooved inclined metal plate a smooth surfaceis always present and wearing away of the wooden frame and,consequently, rough surfaces prevented.

To lessen the friction of the curved bolt or shafts in its inward andoutward movements the socket D is formed with arecess, G, within whichis arranged one or more anti-friction rollers, H, which are preferablyplaced loosely in the said recess, so as to have a rolling motionbackward and forward. It is evident that a good result would also beproduced if the roller was journaled or fixed within said recess.

By the construction given to the bolt and socket less space is requiredto apply the lixture in the janib, and in operation the sash is alwaysnicely counterbalanced by the action of the spring. The metal plate I isformed with a right-angled flange, clearly shown in Fig. 5, which isprovided with a series of openings, within which shoots a bolt or catchto lock the sash in any desired position.

I have shown a peculiarly-constructed looking apparatus, for which Ihave made application for Letters Patent coeval with this presentapplication.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- V l. The plate 0, provided with thecurved socket D, in combination with the curved bolt E, spring F, andfriction-roller d, or its equivalent, operating in connection withtheinclines of the sash, substantially as and for the purpose set forth.

2. In combination With the elements of the above, the recess G formed inthe curved socket D, in combination with the friction-roller H, as andfor the purpose set forth.

3. The inclines f of the sash, formed with the grooves h, in combinationwith the frictionroller d, curved bolt E, spring F, and socket D, withor without the recess G, and anti-friction roller H, substantially asand for the purpose set forth.

To the above I have signed my name this 16th day of December, A. D.1871.

W. HASKELL KING.
